For first time RFduino users on Linux...You need to install WINE.Your user must be a member of group dialout.You need to have a symlink for your WINE com1: port to linux USB linux device for the RFduino.~/.wine/dosdevices/com1 -> dev/ttyUSB0

I don't think so. Arduino has moved to this new approach believing it is way more simpler on newbies, I guess. But, for now, it looks like the only way to add boards and librairies to the new way Arduino does things is via their IDE itself. Which means users have to wait for all their favorite board makers to come up the support for the new way. At least the RFduino team seems to be on top of it.

Not sure what you mean by a real proxy. I think you're saying that your proxy server will not let you connect to rduino.com:8080?

I'm behind proxy and this is only way to be connected to internet, so if put my real proxy into "proxy" field "proxy:8080", I will have access to generic arduino board databases, but if i will put rfduino.com, I will have no connection to internet at all.This mean I will not able to setup new rfduino at any way unless manual.

Where are the back level libraries? I'm running IDE 1.6.0 and I do not want to upgrade to IDE 1.6.3 (and run hundreds of regression tests on my other products). The ONLY link I found is to the most current library.

Yep, me too. The Arduino people are at it again. Not only does installing 1.6.4 not work, it also screws up any 1.6.3 installation you already had working with RFduino 2.3.x installed. Ugh! So going back to it is a bit of a hassle. For me going back to 1.6.3 and then going into the board manager I see it thinks the RFduino is already INSTALLED. Hmm! Then exiting out of the board manager suddenly 1.6.3 is back to working. These versions of Arduino IDE should definitely be in beta mode IMHO.

So until the RFduino Team mentions 1.6.4 stick with the Arduino 1.6.3 IDE.
